OPTIGA™ Trust M Shield2Go Notes to the S2Go Security OPTIGA M:
- Supply voltage VCC is max. 5.5 V, please refer to the OPTIGA™ Trust M datasheet for more details about maximum ratings
- Ensure that no voltage applied to any of the pins exceeds the absolute maximum rating of VCC + 0.3 V
- Pin out on top (head) is directly connected to the pins of the OPTIGA™ Trust M
- If head is broken off, only one capacitor is connected to the OPTIGA™ Trust M
